Abstract
A method for recovering a resource from a CIGS thin-film solar cell to be recycled includes a) providing the CIGS thin-film solar cell, and b) subjecting the CIGS thin-film solar cell to a cooling treatment at a predetermined temperature, such that a light absorbing unit of the CIGS thin-film solar cell can be recovered due to thermal strain difference of materials of the CIGS thin-film solar cell.
